Minnesota Crop News

By: Bailey Tangen, Extension educator, Etienne Sutton, University of Missouri, and Kevin Kuehner, Minnesota Department of Agriculture How much biomass are your cover crops producing, and what does that mean for nutrient retention and soil health? Through the Great Lakes Cover Crop Project, Minnesota farmers are helping to answer that question using a simple protocol based on photos and height measurements. Results will help build practical, local data to guide better cover crop management and nutrient decisions. In this blog post, explore last year’s data from 133 Minnesota fields and how you can participate in 2026. The project and new method for farmers As part of the Great Lakes Cover Crop Project , farmers participate as community scientists by collecting cover crop measurements in their fields. Measuring cover crop growth, or biomass, has historically involved clipping plants within a defined area (e.g., using a quadrat) and then drying and weighing them, which can be time consumi...

By Angie Peltier and Ryan Miller, UMN Extension educators, and Dean Malvick, UMN Extension corn and soybean plant pathologist Curvularia leaf spot in corn. Photo: Dean Malvick March 4, 2026’s Strategic Farming: Let’s Talk Crops session discussed whether foliar corn diseases are likely to threaten Minnesota yields in 2026. This webinar series runs through March and registrations are still being accepted: https://z.umn.edu/SF2026 To watch this episode visit:  https://z.umn.edu/SF2026  http://z.umn.edu/StrategicFarmingRecordings . There is a long list of leaf diseases that can negatively impact a corn crop’s yield potential. The diseases that have been of most recent concern in Minnesota include tar spot, southern rust, Northern corn leaf blight and Goss’s wilt and blight, the diseases that were of focus during this session. Tar spot Three things must be present for disease to occur, a virulent strain of a pathogen, a disease-susceptible hybrid and environmental conditions that ...

Today on the Advancing Nitrogen Smart podcast we speak in-depth about the recently-revised Minnesota Nutrient Reduction Strategy with Matt Drewitz from the Minnesota Pollution Control Agency. What are the goals of the MN Nutrient Reduction Strategy, and how are they being addressed specifically? Are we on track to meet our objectives? How have environmental changes over the years affected our progress? How have wastewater treatment plants contributed to the effort, and what have we learned from them? What kinds of other practices can be leveraged to meet the goals of the NRS, and how should farmers approach these ideas? Who's a farmer's point of contact with questions about adopting these practices? All of this on today's episode, recorded on the road from the recently held Nutrient Management Conference in Mankato, MN. Read the full transcript Guests: Brad Carlson, Extension educator (Mankato) Matt Drewitz Minnesota Pollution Control Agency, (St. Paul) Additio...

This week, we are thrilled to feature Agronomist Matt Leavitt. Matt’s work focuses on integrating new crops that provide broad ecosystem services to our landscapes while helping to diversify and de-risk the economic portfolios of Minnesota crop producers. Originally from Eau Claire, Wisconsin, Matt completed his graduate work right here in the Department of Agronomy and Plant Genetics with Craig Sheaffer and Don Wyse. Currently, Matt serves as the Perennial Grains and Winter Annuals Agronomy Specialist for the Department and the Forever Green Initiative (FGI). In this episode, Matt dives into the most established crops in the FGI portfolio, including Kernza, camelina, winter barley, and hybrid winter rye. He shares his experience working one-on-one with farmers to identify alternative crop species that fit their unique operations, maximizing ecological and economic benefits while reducing overall risk. Beyond the field, Matt also writes extension publications for producers and lecture...

Soybean field being sprayed with pesticide. Over-the-top dicamba use returns to Minnesota for the 2026 season. On Feb. 6, the EPA approved the federal registrations for the following dicamba products Engenia® Herbicide (EPA Reg. No: 7969-507) , Stryax™ with VaporGrip® Technology (EPA Reg. No: 264-1241) , and Tavium® Plus VaporGrip® Technology (EPA Reg. No: 100-1753) 1 .  The new registrations are for over-the-top (OTT) use on dicamba-tolerant (DT) soybeans for the 2026 and 2027 growing seasons (Figure 1). New mitigation measures are required for use to reduce drift, minimize volatility, and protect the environment. As in previous years, state-specific restrictions will be in place for OTT applications of dicamba in Minnesota. Th...
